Web Forms JSON Response
From Online Business Wiki
By default, the system responds to Web Form submissions with an HTML page. You configure that page through the More Customization Options feature. For more flexibility, the system can also return a response in JSON format. Simply add "&JSON=1" to your form action URL. The response you get will look like the following:
- FormProcessV2Response
- success - true
- entityId - the CRM ID of the user submitting the form
- objectTypeId - the type of object the form created - currently, a Booking (61) or a case (2001)
- objectId - the booking or case ID created
- message - any confirmation
- SystemMessage
- success - true/false (typically false)
- message - an error message
